Just got a new harddrive and installed win 7 on my working pc then put it in a new pc with a bunch of spare parts i had laying around and keep getting this error. I plugged in my cd drive from working pc with a win7 boot disc and still got the error. Swapped my bios boot setting several times to no avail and even took the battery out and drained the capacitors and im still getting the same error. No idea what to attempt next.
